Abstract:
An image forming apparatus includes an image forming unit for forming an image; a status conversion unit for converting the multi-value pixel data into status values; plural reference look-up tables each indicating an association between an arrangement of the status values of a target pixel and adjacent pixels in a pixel window and an output data value of the multi-value pixel data to be output; a determining unit for determining a target reference look-up table based on the arrangement; and a generating unit configured to change an input data value of the multi-value pixel data, into the output data value of the determined target reference look-up table, and for outputting the multi-value pixel data to the image forming unit.
